Arduino Band Decoder
Arduino Band decoder with relays for external device control Allows you to read the frequency or band data from your transceiver and switch output relay(s) by the defined rules. This feature allows you to send frequency to other devices such as switching antennas, RX/TX filters, PA, transverses…etc.
The 24 x 24 x 8 cm size metal enclosure taken out from one of the oldest DDS VFO project by VU2WJ; however, we have selected this to accommodate the below mentioned stuffs with enough spacing for wiring. The front panel molded with a 3 mm black acrylic sheet by a local vendor.
Parts List:
- 1. Nano V3.0 Development Board compatible with Arduino,
- 2. DC 12V 16 Channel Relay Module Interface Board with Optocoupler Protection LM2576 Power for Arduino,
- 3. CD4514 4 Bit Latch/4-16 Line Decoder IC DIP-24 Package,
- 4. MAX3232 RS232 to TTL Converter Module,
- 5. 4 line 20x4 LCD Display with Blue Backlight,
- 6. 12 Position SP12T Rotary Switch& knob,
- 7. Connectors including, DC, Din pin9, Mic & Serial Port.
The project consist of modification of 400W Solid State Marine PA, FURUNO PA2500 for automatic LPF and its dual antenna output switching with the Arduino Band Decoder. The front panel of both Band Decoder and PA has been equipped with a 12 pole rotary switch for Automatic and Manual switching of Antennas & Amplifier LPF as required.
